Where is the outline of the smart bracelet? Today, the hospital has a newborn baby every day, but the appearance of the newborn baby is similar, and the language and understanding of the abilities cannot be interacting with the outside world. According to the medical department statistical report, the maternity hospital has a baby's mistake and happening, how to prevent it? Baby smart bracelet scheme designed by a group of large four students can solve this problem.
Recently, a nurses in Anhui Chaohu, Anhui, Anhui Province, take a shower, a new news that the new baby's mistake is attracted online. The newborn mischer incident is not the first time. On the morning of January 8, 2014, there were small Yao and Xiao Sun's lover in Haiyuan County, Anhui Province. Unexpectedly, the two dolls have been hugged. Later, DNA identification finally recited children.
The hospital has a newborn baby every day, and this new life is the most valuable property for each family and parents, but the appearance characteristics of newborn babies are similar, and lack language and understanding cannot be interact with the outside world. According to the medical department statistical report, the maternity hospital has occurred when the infants of the obstetric hospital, but these incidents not only cause serious trauma on their minds, but also damaged the reputation of the hospital, and even faced by litigation and economic compensation.
In September, "Win in Guangzhou" 3rd University Student Entrepreneurship Competition, the infant bracelet developed by a group of large four students in Southern Medical University caused a lot of experts. The team became inspired in internships, and it is considered that the handwriting ring is not safe enough to see the smart anti-theft bracelet of the electronic chip. "If it is in addition to the nurse or other people who take away the baby, the bracelet will automatically trigger alarm system, and open the access control system, and the criminals can't go out." At the same time, the bracelet also has functions such as monitoring baby body temperature, positioning infant position.
Intelligent infant anti-theft system hardware part consists of four aspects
(1) Baby anti-theft label and wristband
The core of the system is a baby anti-theft label design. It is a small radio frequency transmitter. From the moment of label, the electronic anti-theft tag is constantly emitting signal so that the system is always monitored. If unauthorized, any behavior trying to remove or destroy the label triggers alarm. Considering the treatment, bathing, etc., the system is designed, and the system is designed with an active label. The active label is mainly composed of power, microcontrollers, and RF emissions. The microcontroller is used to control the working mode and frequency band of the RF chip, and generate the internal code of the label, and transmit it to the RF chip. The active label RF portion is mainly composed of RF special chips. Wristbands used with labels can be adjusted to accommodate different babies, but they are not reused. Since the newborn baby will reduce weight due to the rapid loss of excess water due to the rapid loss of the body, the wristband can be adjusted according to the weight of the baby. Baby anti-theft tags can be reused, waterproof design, can be cleaned, no allergic reactions.
(2) Card reader design
The card reader provides RF energy to the anti-theft tag, reads data from the anti-theft tag, completes data information processing, and implements application operations and high-level interactive applications. Although various card readers will have great differences and differences due to frequency range, communication protocols, data transmission methods, but all card readers are very similar in the above functions. Since it is remote control, the reading card is not too far away, and it is recognized that the card will enter the induction range. Requires the full-time range of the card reader, has a clear boundary, and the card read card is within 3m; the card is not affected by the human body, cannot be shielded by the human body; the conversion of the card angle is small, the card is not existed. Dead feet. Considering the use of low frequency systems, the CryptagCensus series induction radio frequency identification products can meet the demand, the emission frequency is 153kHz, and the received frequency is 115kHz. There is no impact on the human body without radiation damage, with special crops and equipment such as heart patients, pregnant women, cardiac pacemakers, hearing aids. The received data is transmitted to the server via the RS485 bus and the computer network, and then real-time monitoring and background data processing.
(3) Export Monitor
Export monitors are installed near the controlled zones (such as obstetrics and gynecology diseases) and continuously emit radio frequency signals. Once the infant carrying the anti-theft tag enters an emission area of an exit monitor, the anti-theft tag that receives the exit monitor signal will immediately send alarm information to the control computer through the receiver. The system continuously monitors the operating status of the export monitor and timely alarms when the device is wrong or when it is destroyed. The monitoring range of the monitor can be adjusted in the range of 2 to 3m.
(4) Computer control system
Computer control systems include various servers and terminal computers in communication gateways and anti-theft systems. Communication gateway is installed in weak interstivities in the stations of the obstetrics and gynecology, for processing, processing data on each reader and export monitor this floor, manages the work of each card reader and export monitor this floor, while TCP / IP is connected to the server and the hospital's local area network, including access control system, security room, and computer center and other monitoring alarms.
Function and value of smart bracelet alarm system
Prevent malicious exchange babies:
The infant wristband is designed as a one-time, once the wristband is worn, it is open again, the system alarms. This prevents human malicious to exchange babies to avoid disputes that may cause hospitals and patients.
Prevent stolen baby:
In the past few days of birth to the hospital, in addition to special circumstances, the mother and baby will stay in a particular monitoring area, in which the system is detected in the safe area. Once the baby is illegally stolen (no authorized area where the baby leaves the safe care area), the system is immediately alarm prompt.
Retrocence inquiry:
Infant activity small areas, medical staff and parents enter areas, alarm events, etc., the system will automatically record, and provide a basis for the afterward query.
Revenue for hospital:
Mother and baby's wristbands are very delicate, and they can be sold to their families in the discharge as a birth commemoration. Sell to the family in each 150 yuan, 1 year, according to the computation of 2,500 infants, you can generate 375,000 yuan each year; or you can charge normal usage at hospitalization, charge 15 yuan for 15 yuan per day, 1 year compared 2,500 babies For each baby's hospitalization 3 days, you can create 112,500 yuan per year.
Improve hospital image and management level:
Using maternal and child identification and newborn anti-theft management system, the automation management of the system is realized, eliminating the concerns of newborns, reducing hospital management hidden dangers, and improving the image of the whole hospital.
